If two sets are disjoint, then what region represents the union of their complements in a Venn diagram?

1 answer:

5 0

Let A and B be disjoint, the complement of A is everything not in A and the complement of B is everything not in B. The union of the two is therefore everything that is not in A or everything that is not in B, so it must be the entire universe.

Please help im being timed <br><br> Inverse of f(x)=15x+4

rusak2 [61]

Answer:

$f^{-1}$ (x) =

Step-by-step explanation:

let y = f(x), then rearrange making x the subject

y = $\frac{1}{5}$ x + 4 ( subtract 4 from both sides )

y - 4 = $\frac{1}{5}$ x ( multiply both sides by 5 to clear the fraction )

5y - 20 = x

Change y back into terms of x with x = $f^{-1}$ (x) , then

$f^{-1}$ (x) = 5x - 20
